REGENERATIVE MUTATION PROCESSES RELATED to the SELFDECOMPOSABILITY of SIBUYA DISTRIBUTIONS
(Cambridge University Press, 2019)
Copyright © Cambridge University Press 2018. The Sibuya distribution is a discrete probability distribution on the positive integers which, while Poisson-compounding it, gives rise to the discrete-stable distribution of ...
Vigilance and collective detection of predators in degus (Octodon degus)
(BLACKWELL, 2006-09)
Individuals of social and partially social species typically reduce their vigilance activity when foraging in groups. As a result, per capita risk of predation decreases and individuals allocate more time to foraging and ...
Numerical simulation of cation exchange in fine-coarse seawater slurry pipeline flow
(Elsevier Ltd, 2018)
Slurry pipelines transporting a coarse—the comminution product—and a fine fraction, both in the presence of
seawater, can cause an alteration of the liquid phase chemical composition. In the present paper, we present ...
Activación alcalina de residuos de minería aurífera de veta para la fabricación de morteros
(Fondo Editorial EIA - Universidad EIA, 2021-05-31)
Los residuos mineros (RM) generan grandes problemas ambientales debido a la alta y progresiva explotación de minerales y su consecuente disposición. La activación alcalina es un método ampliamente utilizado para la fabricación ...
Environmental assessment of mercury pollution in urban tailings from gold mining
(Elsevier Inc., 2013)
It is well-known that small-scale artisanal mining is a source of mercury emissions into the environment, mainly from the use of rudimentary technologies that use mercury amalgamation in the extraction process. Mines near ...
Morphological differences in a population of Rufous-collared Sparrow (Zonotrichia capensis, Statius Muller, 1776) (Passerine, Emberizidae) at different elevations in the Tropical Andes
(Revista Biota Neotropica, 2020)
Populations that breed along steep elevation gradients show diverse physiological and morphological changes in response to the different environmental conditions. The latter has been discussed by Bergmann's and Allen's ...
On the seasonal effect of landscape structure on a bird species: the thorn-tailed rayadito in a relict forest in northern Chile
(SPRINGER, 2007-08)
Forest bird species exhibit noticeable seasonal behavioral changes that might lead to contrasting effects of landscape pattern upon species abundance and performance. We assessed if the effect of patch and habitat attributes ...
Extrapair paternity in two populations of the socially monogamous Thorn-tailed Rayadito Aphrastura spinicauda (Passeriformes: Furnariidae)
(Wiley, 2020)
Studies on extrapair paternity (EPP) are key to understanding the ecological and evolutionary drivers of variation in avian mating strategies, but information is currently lacking for most tropical and subtropical taxa. ...
Walking Like Dinosaurs: Chickens with Artificial Tails Provide Clues about Non-Avian Theropod Locomotion
(2014)
Birds still share many traits with their dinosaur ancestors, making them the best living group to reconstruct certain aspects
of non-avian theropod biology. Bipedal, digitigrade locomotion and parasagittal hindlimb movement ...
